Xws li cov khoom siv tho, laum hlua, downhole fais fab drilling cuab yeej, stabilizers, shock absorbers, vibrators thiab lwm yam cuab yeej.
Muaj peb hom cone khoom, pob zeb diamond khoom thiab scraper khoom:
(1) lub khob hliav qab, uas yog tsim los ntawm lub cev laum, claw claw, bearing, dej qhov muag, thiab lwm yam. qauv, nws muab faib ua ntim (los yog unsealed) dov bearings thiab kaw (los yog unsealed) zawv zawg bearings.
(2) Pob zeb diamond laum khoom, uas yog Ameslikas txwv rau kev tsim nyuaj, tab tom nthuav lawv ntau yam thiab kev siv. Txawm hais tias tus nqi ntawm lub laum me ntsis yog siab, nws muaj lub neej ua haujlwm ntev, thiab yog tias qhov kev xaiv tsim nyog, nws tuaj yeem ua tiav kev lag luam zoo dua.
(3) Lub scraper me ntsis muaj cov qauv yooj yim, kev tsim khoom yooj yim, thiab qhov ceev ntawm kev sib tsoo mos yog ceev, tab sis lub zog loj thaum drilling, thiab nws yooj yim rau kev puas tsuaj rau cov cuab yeej drilling thiab cov cuab yeej. Nyob rau hauv xyoo tas los no, ib yam tshiab ntawm kev xyaum xyaum me ntsis yog tsim, uas yog embedded rau lub laum me ntsis matrix nrog tshiab hnav-resistant cov ntaub ntawv ntawm txawv geometric duab, uas yuav hloov mus rau ntau yam lithologic formations, thiab yuav drilled ntawm kev kub ceev, thiab nws cov txiaj ntsig kev lag luam yog nce ntxiv.
Lub ntsiab lus dav dav rau tag nrho cov downhole drilling cuab yeej los ntawm square laum yeeb nkab rau laum me ntsis, uas yog tsim los ntawm square laum yeeb nkab, laum yeeb nkab, laum dab tshos, stabilizer sib koom thiab lwm yam khoom siv. Lub luag haujlwm yog ua si lub laum me ntsis, xa cov tshuab hluav taws xob uas yuav tsum tau ua kom tawg lub pob zeb mus rau lub laum me ntsis, siv lub zog drilling mus rau hauv qab ntawm lub qhov dej, thiab thauj cov dej ntxuav dej mus rau qhov dej thiab ua lwm yam kev ua haujlwm downhole.
